' FAUCET Filled Nov. s, 193e gmc/Wto@ wid/whirl Gandalf Patented Jan. 4,1938 UNITED STATES PATENToI-Flc 1 Claim.

My invention relates to improvements in faucets, and it consists in theconstructions, combinations, and arrangements herein described andclaimed.

The invention is particularly directed to that type of faucet in whichauxiliary means is provided for cutting off the flow of water so as topermit the removal of the washer, such as a fiber washer, and thereplacement of a new washer, without the necessity of manipulating othercutoifs which are generally located some distance away.

An object of the invention is to provide a simple device which is easilyaccessible and which will act to positively cut off all flow so as topermit the removal and replacement of the washer on the main valve stem.

A further object of the invention is to provide valve seats which willnot cut the washer on the main valve stem but which will permit thewasher to make a more effective closure the longer the washer wears andthe tighter it is screwed down on the valve seat.

A further object of the invention is to provide a device of the typedescribed which can be manipulated by a simple tool, such as a screwdriver, a wrench, or the like.

A still further object of the invention is to provide a faucetconstruction which is applicable to the ordinary compression bibb and tosuch forms of faucets as the upright basin cock. Other objects andadvantages will appear in the following specification and the novelfeatures of the invention as will be particularly pointed out in theappended claim.

My invention is illustrated in the accompanying drawing, in which:-

Figure 1 is a vertical sectional view through a compression bibbcontaining one embodiment of my invention,

Figure 2 is a fragmentary sectional view through a washer showing thelatter compressed on its seat.

Referring now particularly to Fig. 1 I have shown therein a faucetcomprising a body portion 4 having a spout 5. An extension 6, which isthreaded to engage a water pipe 1, constitutes an inlet. An extension 8which is threaded internally receives the main valve 9 which iscontrolled by a Valve stem Il) and a handle II. The valve 9 is providedwith a washer I2 of fiber, rubber, or other suitable material. Apartition I3 separates the water chamber I4 from the spout 5.

This partition is provided with a passageway I5. The upper end of thispassageway I5 is controlled by the valve 9 and washer I2. It will benoted that the valve seat has an annular ridge I6 against which thewasher I2 can bear, and it also has a tapered portion I'I adjacent tothe ridge I6 which acts as an extension of the valve seat, as 5 thevalve is screwed downwardly. When the washer I2 begins to wear or isforced tightly against its seat, it will be observed that a greaterbearing surface comes into play, part of this bearing surface being theseat I1, as shown inFig. 2. l0 Thus the more the washer wears thegreater the bearing surface and the less the chance for leakage.

The upper part of the extension 8 has a packing gland I8 with the usualrubber washer I9, supl5 ported by the metal washer I9a, and screw cap 20for compressing the gland to prevent any leakage.

On the bottom of the faucet is an extension 2l which is threadedinternally to receive the threaded portion of a valve stem 22. The outerend of 20 this valve stem is preferably squared as shown at 22a so thatit can be turned by a wrench and the end is provided with a kerf 22h sothat it can be manipulated by a screw driver. A packing gland and washer23 is provided which is compressed 25 by a threaded compression member24 so as to prevent leakage.

The auxiliary valve 25 is formed by beveling the end of the valve stem22 and this valve seats on a machine and tapered surface 26 so as to 30make a tight closure.

From the foregoing description of the various parts of the device theoperation thereof may be readily understood. Normally the valve stem 22is unscrewed so as to permit a free flow of 35 water from the chamber I4to the passageway I5. Normally also the washer I2 is screwed down on itsseat to shut o the water. By manipulating the handle Il the valve may bewithdrawn so as to permit the water to flow from the pipe 'I 40 throughthe chamber I4 and passageway I5 and the nozzle in its discharge.

When the washer becomes worn, all that it is needed to do to change it,is to turn the valve stem 22 so as to bring the valve 25 in contact 45with its seat, thus closing the passageway I5 and permitting the cap 2l)and the valve 9 to be removed. lWhen the washer is replaced and theparts are again brought into position, as shown in Fig. 1, the valvestem 22 can be retracted, thus 50 permitting the water to again haveaccess to the passageway I5 which is of course controlled by the handleII and valve 9 in the usual manner.

It is not necessary to leave the faucet to eiect the removal andreplacement of the washer I2 55 2W" .l Y Y of the device and there is noleakage while this is being done, since the machined surfaces of theauxiliary valve and its seat tend to effect a complete closure when thevalve is on its seat.

I claim: f

A faucet comprising a water chamber having an inlet, an inclined spout,a partition having a thickened intermediate Vportion and an auxiliaryvertical chamber of greater length than its width in the thickenedportion, the partition being inclined at an angle to the horizontal andforming part of the inclined wall of said spout. said auxiliary chamberforming a communication between the water chamber'and the spout, a, mainvalve seat on the inclined partition at the upper end Y chamber, theupper end of said auxiliary cham- 10 ber` being flared.
